Use and Care Manual

The exhaust pipe must maintain adequate clearances and be insulated with a
fireproof material if it passes through walls made of flammable materials. Consult
local codes and vent pipe manufacture documentation for proper material
selection and installation requirements.
If the heater will be installed in a building that has a system that
maintains a negative pressure, it is possible for a back-draft to allow
outside air to be pulled into the heater while not in operation. This
can create a situation where freezing might occur within the heater.
Please consult a professional for a properly designed venting
solution or contact qualified technician for guidance.
AIR INTAKE PIPE ASSEMBLY
1. Drill 2 small holes at the end of the air intake pipe.
2. Slide the pipe over the air intake terminal.
3. Using a level, ensure the pipe is straight up and down.
4. With self tapping screws, attach the pipe to the air intake terminal.
5. Apply a bead of silicone around the pipe and air intake terminal, ensuring an air
tight connection.
1. Use manufactures universal Adapter to connect the vent pipe to the unit.
2. Then follow the Manufactures vent pipe assembly guidelines and standard vent
pipe location selection diagram below.
4140
- Air intake pipe may be ABS, PVC, galvanized steel, corrugated aluminum or other
materials acceptable to local codes.
- The heater requires a direct vent. Exhaust vent must be of AL 29-4C® Stainless
Steel vent directly to the outside of the building.
- The exhaust vent will have been tested to meet Underwriters Laboratories, Inc. to
UL 1738 and ULC-S636.
- The system must use outside air for combustion. Ensure the incoming air is not
contaminated by any potential source of fumes or chemicals.
- Avoid any dips or sags in horizontal pipe runs.
- Ensure vent piping is supported every four (4) feet (horizontal runs) or six (6) feet
(vertical runs) or in accordance with local code requirements.
- Do not reduce the diameter of the vent piping.
- Ensure all vent connections are installed, properly connected, and sealed air tight
per manufacturer's instructions.
- Any vent pipe seams should be installed so they are oriented on the top of
horizontal pipe runs.
- Slope exhaust piping towards the exhaust terminal with a 2% slope (1/4 inch per
foot; 19 mm/ m) to ensure rain or any accumulating condensate near termination
are drained.
- A condensate collector is required for this system when there is a vertical vent
configuration. A condensate collection point should be installed on the vertical run
of piping just prior to the heater to ensure proper condensate drainage. Check with
local codes for proper disposition and handling of condensate water, an air gaped
drain is usually required and in some cases a condensate neutralization system is
also required.
- Do not store hazardous or combustible materials near the vent piping
- Ensure the air intake and vent termination points are at least 12” (300 mm) above
any possible snow accumulation level. The flows must not be impeded by snow or
debris.
- Ensure the air intake and vent termination points are at least 24” (600 mm) from
any obstruction or other objects.
